I have a 30-30 in a contender and it has just about no freebore is this a job I can do with hand tools and a reammer,or do I need to send it of to a gunsmith

The 30-30 barrels varied across the years with freebore dimensions and chamber/barrel alignment. Perhaps a new barrel from Bullberry Legacy Barrels will be less expensive than a rechamber to modify the freebore.

If you are good with tools and understand that a "throating reamer" will cut fast, then renting the reamer and doing it yourself isn't difficult nor expensive.

i have a nice throater you could use for postage ...  straight 3 degree included taper from 0.313 down  ...  i do require a deposit which is fully returned when the good reamer is returned.  

the only hard part to throating is to not to cut too much ...  plan ahead and be gentle

Take him up on it. It is a simple job if you ever took machine shop in High School.

are you sure you want freebore ,etc on your contender

I had great success in the days of IHMSA with my 10" contender/ old 14 twist factory stock barrel.

It shot the 311466 Loverin well enough to hit a 39 and then 7 of 10 beer cans at 200yds in a shootoff

yes, this is a 1 in 10 twist with just about no freebore 23 in barrel  I will be shooting 230 gr paper patched bullets so good bit of freebore is a must , I have other 30cal barrels for shooting lighter bullets from pistol platforms .

Fitzpatrick,

I am very curious as to the 230 grain PP bullet you mention. 

Apparently your bullet diameter is straight "patch to groove" like the old Lyman 301620.???

You would not need a long freebore with a Dual DIameter bullet:

Base band/major diameter at "patch to groove" that fits in the case neck and a "patch to bore" body

that slips snugly on to the lands.

It s a LBT design that I size down to .305 then patch, the base is then .311 with a taper that drops to .308  with the nose of the bullet  being .303 which fits into the riflings with a slight engraving  , This is going off the bullet that I use in the 30-06 and 308 . and it is cast from pure lead with 1-40 tin added so a good expanding hunting bullet . 

 I shoot a lot of paper targets but all research and development is to achieve a better hunting bullet .

Look like that would be good for my 40-65.

Would like to see the cast bullet and a wrapped one of those.

So DD pp’ed bullets work for smokeless then?

Thank’s Fitzpatrick 

I’m inspired to get my stuff out and have another go.

I have been sleeping and having fun with mild  pb bullets for the last few years. 

If you rub some grit on non lubed  patched bullets you throat will get longer quickly enough.( attempt at humour)

Yea , I also heard that if I just put some valve grinding compound on a bullet, tap the end with threads install a bolt and use a cordless drill that I could increase the throat, But I think I will try a throater first and see how that works.

  In my Savage model 340 and with the reliable Winchester model 94 I have good groups with bullet up to 200 gr. but with the COL length limit and the 1/12 twist that seems to be my wall. With the Contender I'll have no limit on COL and the 1/10 twist should do well with the heavies.

Look up Buffalo Arms   JIM# 403380E.

The base diameter is about 0.410-0.411 and the Patch to bore body is about 0.400

that is with Seth Cole 55W paper.
